A container including a finish, a sidewall portion, a base portion, and an inwardly directed rib member. The finish has a thread portion and an opening formed by the finish. The sidewall portion extends from the finish. The base portion extends from the sidewall portion and encloses the sidewall portion to form a volume for retaining a commodity. The inwardly directed rib member is disposed circumferentially about the finish.

1. A plastic bottle comprising: a body comprising: a shoulder;a cylindrical sidewall;a closed base extending inwardly from said sidewall; and,a volume for retaining a commodity, said shoulder, said cylindrical sidewall, and said closed base collectively form an interior defining said volume; and,a neck comprising: a support ring;a continuous annular wall extending upwardly from said shoulder to said support ring;an annular sealing ridge axially spaced from said support ring;a circumferential sidewall comprising: a rim defining an open top in a first plane;an annular groove formed within an outer surface of said circumferential sidewall and spaced from said rim, said annular groove disposed in a second plane extending generally parallel to said first plane; and,a helical thread protruding outwardly from said outer surface, said helical thread having an uppermost portion spaced from said annular groove and a lowermost portion spaced from said annular sealing ridge, and said helical thread capable of receiving a removable threaded closure. 2. The plastic bottle according to claim 1, wherein said second plane is generally parallel to a third plane corresponding to the closed base. 3. The plastic bottle according to claim 1 wherein said neck defines a generally unobstructed continuous interior surface opposite said annular groove. 4. The plastic bottle according to claim 1, wherein said annular groove comprises a depth in the range of about 0.25 mm to about 1 mm. 5. The plastic bottle according to claim 1, wherein said annular groove comprises a depth of 0.51 mm. 6. The plastic bottle according to claim 1, wherein said annular groove comprises a radius in the range of about 0.15 mm to about 0.50 mm. 7. The plastic bottle according to claim 1, wherein said annular groove comprises a radius of 0.35 mm. 8. The plastic bottle according to claim 1, wherein said annular groove comprises an internal angle in the range of about 30° to about 90°. 9. The plastic bottle according to claim 1, wherein said annular groove comprises an internal angle of about 60°. 10. A container comprising: a closed base; and,a sidewall having: an upper portion; and,a cylindrical lower portion upwardly extending from said closed base to define a cavity for retaining a commodity;a neck comprising: a rim having: an inner upper edge defining an open top for receiving and dispensing said commodity;a rounded outer upper edge defining a first radial thickness;an annular lower portion;a circumferential interior surface axially extending between said inner upper edge and said upper portion of said sidewall, said circumferential interior surface being continuous and unobstructed throughout;a cylindrical wall having a helical thread formed on an exterior surface, said helical thread defining a second radial thickness, wherein said second radial thickness is greater than said first radial thickness of said rounded outer upper edge;a lower sealing ring axially spaced below said helical thread and extending outwardly from said exterior surface, said sealing ring being sealingly engagable with a closure for closing said open top to store said commodity in said cavity;a circumferential groove formed on said exterior surface and separating said annular lower portion of said rim from an upper end of said helical thread. 11. The container according to claim 10, wherein said circumferential groove defines an upper radial axis generally horizontally disposed generally parallel to a lower radial axis defined by the base portion, and said circumferential groove is confined to a first plane extending generally parallel to a second plane defined by open top. 12. The container according to claim 10, further comprising a support ring extending outwardly from said exterior surface of said neck, said support ring being disposed axially below said helical thread such that said helical thread is disposed between said support ring and said circumferential groove. 13. The container of claim 10, wherein a second planar vertical portion of the exterior surface extends away from the circumferential groove and away from the closed base, and between the second planar vertical portion and said rim, the exterior surface curves radially inward towards the open top. 14. A container comprising: a circumferential finish surrounding a central vertical axis and having a thread portion and an opening formed along a top edge of the finish in an opening plane transverse to said central vertical axis, said thread portion being formed to threadedly engage a closure member, said finish having an exterior surface with a variable diameter and a generally unobstructed interior surface extending continuously along said central vertical axis, said thread portion being disposed on said exterior surface;a neck extending downwardly from said finish along said central axis;a sidewall portion extending from said neck;a base portion extending inwardly from said sidewall portion and enclosing a lower end of said sidewall portion to form a volume for retaining a commodity, said base portion confined to a base plane transverse to said central axis;a circumferential groove formed within said exterior surface of said finish between said top edge and said thread portion, the circumferential groove having a sloped upper wall portion and a sloped lower wall portion joined at an apex confined to a groove plane extending generally parallel to the base plane;a first annular portion of the exterior surface extends along said central vertical axis between the circumferential groove and a start of the thread portion;a second annular portion of the exterior surface extends upwardly along said central vertical axis from said circumferential groove toward said top edge;a curved annular portion of the exterior surface extends axially between the second planar annular portion and said top edge of the finish and curves radially inward towards the opening;a support ring extending from at least one of said finish, said neck, and said sidewall portion, said support ring being disposed below said thread portion such that said thread portion is disposed between said support ring and said circumferential groove; anda sealing ridge extending from at least one of said finish and said neck, said sealing ridge being sealingly engagable with the closure member and disposed below said circumferential groove and said thread portion such that said sealing ridge is positioned between said thread portion and said support ring, said sealing ridge extending radially outward further than said thread portion and said top edge extend radially outward.
